Sorry to keep bothering you with questions about an old game, but I am totally hooked on it!

Anyway, I have a few questions on file locations. I know that there is a text file you can open to look at what endings you are going for, I assume this is the save file?

So I have been trying to find it and unable to, and was hoping for help in locating the save file (and whatever file you look at to see the hard data for what endings you have points in, if it's not the save file).
